A composition at least two different phosphites, one of which is derived from an alkylated m-cresol, wherein the composition is a liquid at ambient conditions. The other phosphites may be derived from alkylated cresol, alkylated phenol or other alkylated hydroxyaryl compounds. The cresol may be mono-alkylated or di-alkylated with a C1-C18 alkyl group.

Tandem‐catalyzed hydroaminomethylation is a useful tool for synthesizing linearamines from olefins and amines in an atom‐efficient manner. To enable the coupling of highly functionalized, hydrosoluble amines with non‐water‐soluble olefins, this reaction must be transferred to aqueous biphasic solvent systems. In this work, we systematically evaluate reaction conditions to provide a selective hydroaminomethylation

A phosphite composition comprising at least two of a tris(dibutylaryl) phosphite, a tris(monobutylaryl) phosphite, a bis(dibutylaryl)monobutylaryl phosphite, and a bis(monobutylaryl)dibutylaryl phosphite. The inventive phosphite composition is a liquid at ambient conditions. The inventive phosphite is a reaction product of a phorsphous trihalide with an alkylate composition having a molar ratio of monobutylaryl alkylate to dibutylaryl alkylate that is higher than 2:1 and equal to or lower than 5:1.

The invention is directed to various alkylaryl phosphite compositions that ideally are suitable for use as secondary antioxidants in polymers. In one aspect, the phosphite composition comprises a tris(monoalkylaryl)phosphite in an amount from 51 to 95 weight percent; and at least one of: a bis(monoalkylaryl)dialkylaryl phosphite; a bis(dialkylaryl)monoalkylaryl phosphite; and a tris(dialkylaryl) phosphite. The inventive phosphite composition is a solid at ambient conditions. The invention also relates to alkylate compositions and processes for forming such alkylate compositions and such phosphite compositions.
Catalyst systems and methods for making and using the same are disclosed. A catalyst composition is provided that includes a catalyst compound supported to form a supported catalyst system, the catalyst compound including: where each of R
